The Boston Scientific MACH1 VL3 6F Coronary Guiding Catheter (REF H74934356710) is a single-use diagnostic and interventional guiding catheter designed to deliver interventional devices to the coronary anatomy. The MACH1 platform is engineered with a proprietary three-layer shaft construction intended to provide a balance of torque response, kink resistance and backup support during percutaneous coronary procedures.

Key Features
- Three-layer shaft construction combining an inner lubricious liner, a stainless steel braid and an outer polymer jacket for torque transmission and pushability.
- VL3 (Voda Left 3) curve designed for engagement of the left coronary ostium with extended backup support against the contralateral aortic wall.
- 6F (French) outer diameter compatible with a broad range of 6F-compatible interventional devices.
- Large lumen design intended to accommodate contemporary balloon, stent and adjunctive therapy systems.
- Atraumatic soft tip designed to reduce the risk of vessel trauma during engagement.
- Radiopaque markers and shaft visualization to aid fluoroscopic placement.
- Sterile, single-use packaging.

Clinical Applications
- Introduction of interventional and diagnostic devices into the coronary vasculature.
- Selective engagement of the left coronary artery during percutaneous coronary intervention (PCI).
- Procedures requiring enhanced passive backup support, such as interventions on tortuous, calcified or chronically occluded vessels, in accordance with the manufacturer's Instructions for Use.
- Typically used via a transfemoral access approach; refer to the IFU for access route compatibility.
